Vitamin D (cholecalciferol) - The Sunshine Vitamin | Vitamin D (cholecalciferol)

 Vitamin D (cholecalciferol) – The Sunshine Vitamin


Vitamin D


Vitamin D is the Sunshine Vitamin – and its main role in the body is to help build a very strong immune system. Including vitamin D2 (ergocalciferol), vitamin D3 (cholecalciferol), 25-(OH) D3 (calcifediol), 1–25 (OH) 2 D3 (calcitriol), and dihydrotachysterol


Known as the “Sunshine Vitamin” vitamin D is important for a strong immune system response when required to help combat disease.

SUNFACTS: for maximum daily intake of vitamin D before you put your  sunscreen on to optimize your health benefits : ( for white people 15 minutes per day, brown people 30 minutes per day and black people 120 minutes per day).

Vitamin D is fat soluble and is ingested either by sunlight or food.

The action of the sun’s ultraviolet rays on the skin activates a form of cholesterol which converts to vitamin D.

Ingested vitamin D is then absorbed through the intestinal wall with the aid of bile and transported to the liver for storage, other deposits can be found in the skin, brain and bones.

The body can store large amounts of vitamin D.




Vitamin D aids in the absorption of calcium and the breakdown and assimilation of phosphorous required for bone formation.

Helps the synthesis of enzymes in mucous membrane transport available calcium

Regulates the transport of calcium with the parathyroid hormones

Necessary for normal growth in children

Assists in normal blood clotting, normal heart function and a stable nervous system

Assists with strong healthy teeth

Calcium absorption and mineral deposition into the skeleton

Cell growth and development, particularly white blood cells and epithelial cells

Activity and response of white blood cells against infection


Increased Risk of Deficiency


Myopia – nearsightedness

Inadequate sunlight exposure, northern latitudes, winter season

Vegetarian diets

Older age groups

Poorly developed muscles

Fat mal-absorption

Breast-fed infants

Chronic kidney disease


Signs and Symptoms of Deficiency


In Children

Delayed growth and development (delayed ability to sit up, stand or walk)

Muscular numbness, tingling and spasm

Irritability and restlessness

Rickets: softening of bones, spinal deformities, bowed legs and knock knees, enlargement of the rib–sternum joints

Poorly formed teeth and enamel

Impaired immune response susceptible to infection

In Adolescents

Impaired growth of bones and muscles

Swelling and pain at the end of long bones, especially at the knee

Increased risk of infection and low immunity

In Adults

Loss of bone mineral from the skeleton

Increased risk of osteoporosis/ osteomalacia and fractures

Rickets – softened bones

Hearing loss and ringing in the ears

Muscle weakness, particularly around the hips

May increase risk of colorectal and breast cancer

May increase risk of high blood pressure

Increased risk of infection and low immune response

Good Dietary Sources

Salmon, Eggs, Tuna, liver, milk fortified with vitamin D, fish liver oil, sunflower seeds


The action of sufficient sunlight on the skin satisfies the bodies need for vitamin D.

SUNFACTS: for maximum daily intake of vitamin D before you put your  sunscreen on to optimize your health benefits : ( for white people 15 minutes per day, brown people 30 minutes per day and black people 120 minutes per day).

Some factors can inhibit the action on the skin: pollution, clouds, window glass or clothing, sunscreens

Recommended daily allowance (RDA)

Children               10mcg (400iu)

Adults                   10mcg

Pregnancy, Breast feeding, Infants, Children and Adolescents require as much as an adult dose of vitamin D.


Increased frequency of urination

Loss of appetite




Muscular weakness



Calcification of the soft tissue of the heart, blood vessels and lungs

Tetany – a condition marked by intermittent muscular spasms, caused by malfunction of the parathyroid glands and a consequent deficiency of calcium.

Reproductive system:



Acne, bed sores, Burns, Carbuncles, Eczema, Psoriasis, Shingles                                                                                                 (herpes zoster)

Teeth and Gums:



Aging, Alcoholism, Backache, Cancer, Fatigue, Insomnia, Kwashiokor, Pregnancy, Rheumatic fever and Stress


Vitamin A and D and Colds

Studies have shown that 80% of chronic cold sufferers showed a significant reduction and severity of

bouts of the common cold when supplemented with Vitamins A and D.
